VAC Oil Pump Upgrade Kit BMW M5/Z8 (S62/E39)

Ever have an oil pump sprocket retaining nut back off and lose oil pressure?

How about shearing off the oil pump shaft with the sprocket and nut still attached?... Chances are you lost that engine.
While this isn't very common on the V8 engines, It can happen, and we know many
of you looking at this may have a heavily modified engine. Why risk it...?
Our kit eliminates all failure modes permanently while retaining serviceability
of the pump.
Some people believe it is enough to weld the OEM bolt on, or use a special nut and/or safety wire, however in these cases this does not solve the shearing of the shaft (completely off!) and in some cases can make things worse.

Note: a oil pump sprocket is not needed in the S62 kit, your OE sprocket
is retained.

**Kit install is simple but requires a press.**
-If you would like, you can also ship your oil pump to us and have our experienced machine shop staff recondition and install your new VAC kit for a fee.
-You will receive your upgraded oil pump ready to bolt in.
